Problems solved by technology

Since BICC CIC is represented by 32 bits, the range of BICC CIC between two service nodes reaches 0 to 4,294,967,295, but the BICC protocol does not give how to manage and apply the configuration of BICC CIC data and BICC CIC in the BICC network. The method of route selection and the maintenance and management of BICC CIC such as a large-scale call instance relationship, that is, how to manage and apply call instances between service nodes has not been considered in the current BICC protocol

Embodiment Construction

[0022] The method of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] On the basis of the original technology of the BICC protocol, a BICC virtual trunk corresponding to the BICC CIC is set up, and the virtual trunk number is used to identify it. Set the BICC virtual trunk as a logical entity. Set the corresponding BICC virtual trunk configuration table, which at least includes the virtual trunk group number, virtual trunk number, and CIC of the BICC virtual trunk group set according to the BICC virtual trunk, and can also include CIC master or non- Master control mark and CIC available mark etc. There is a one-to-one correspondence between BICC virtual trunks and BICC CICs, so there is also a one-to-one correspondence between virtual trunk numbers and BICC CICs. The mapping relationship between BICC virtual trunks and BICC CICs can be compared to physical trunk circuits in ISUP ci...

Abstract

This invention discloses a method for managing and applying a call example. The said method presets and labels BICC virtual relay corresponding to the call example code of idenlified call example(BICC CIC), BICC is similar to the relay circuit in narrow band exchange network to divide BICC with the same attribute into a BICC virtual relay group to seta BICC virtual relay matched list including BICC virtual relay group number, BICC number and BICC CIC and a BICC relay group matched list including BICC relay group number, route or subroute number and BICC relay selection way to change the management appliance to the call into management to BICC relay.

Description

technical field [0001] The present invention relates to a bearer independent call control (BICC, Bearer Independent Call Control) protocol, more precisely a method for managing and applying call instances in BICC. Background technique [0002] BICC protocol, as an important supporting tool for the evolution of traditional telecommunication network to integrated multi-service network, is developed on the basis of ISDN User Part (ISUP, ISDN User Part) protocol of narrowband No. 7 signaling, and belongs to a kind of broadband packet signaling . The circuit identifier code (ISUP CIC, Circuit Identifier Code) in the general narrowband SS7 corresponds to a specific physical circuit, and the data configuration and trunk selection of ISUP CIC are "bound" with the specific physical trunk circuit. ", therefore, the operation of the trunk circuit is the operation of the corresponding ISUP CIC, and a basic feature of the BICC protocol is that the call control layer is separated from th...
